php - DomDocument/DOMXPath - How to get HTML Dom element by itemprop and img src -


i working on script getting data html dom elements.

here code:

<?php $url = 'http://www.sportsdirect.com/nike-satire-mens-skate-shoes-242188?colcode=24218822'; libxml_use_internal_errors(true);  $doc = new domdocument(); $doc->loadhtmlfile($url);  $xpath = new domxpath($doc);  $name = $xpath->query('//span[@id="productname"]')->item(0)->nodevalue;  echo $name; ?>

this code taking text inside <span id="productname"></span>. know how data elements specific class or id.

i don't know how can src="http://adres-to-image.com/img.png" (pure example) image tag or how can elements not have id or class have attribute itemprop, example <div itemprop="name"></div>

  1. how can image src ?
  2. how can elements itemprop ?

thanks in advance!

for examples:

$xpath->query('//img/@src)->item(0)->nodevalue

this means

select src attributes of img tags , value of first

$xpath->query('//div/[@itemprop="name"])->item(0)->nodevalue

this means

select divs itemprop attr equals name , value of first.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
